To all whom z't may comm.

yBe it known that I, CoLvIN L.JoHNsoN,

a citizen of the United States, and a resident of the city of St. Louis, State o Missouri, have invented certain new and useful Improvements in a S are-Wheel Lock; and I do hereby declare t at the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to -an improved lock for holding a spare vehicle wheel locked on a wheel carrier against unauthor-l ized removal. v

It is an object of this invention to provide a lock for use on a bolt of a spare wheel carrier to hold the `spare wheel lockedin position when a latch member of the lock is set to prevent the lock from being removed from the bolt.

'It is also an object of the invention to provide a carrier bolt with a lock adapted to be threaded onto the bolt, and locked thereon against removal by operating a key controlled latch member.

It is a further object of the invention to provide a spare wheel lock ada ted for use on a carrier bolt and operable y means of a key to cause a rotatable portion of the lock to be locked with a non-rotatable member to prevent the rotatable portion from being removed from' the carrier bolt.

Itis an infortant object of thisfinvention to provi e a sim le and elective lock whereb a. spare vehic e wheel may be readily loc ed upon a carrier by simply subf stituting the locking members of this in-y vention for the customary carrier bolt nut.

Other and further important objects of this invention will be lapparent from the disclosures-in' the specification and the accom anying drawings.

e mventlon Sllnaa preferred '.form) is illustrated in the and hereinafter more-idly .desa-ibas. f' `Onthedrawingsz f -Figure 1 .is a diametrical section taken throughv aspare vehicle wheel sup rted on a carrier and locked in position y means of a lock embodying the principles of this` invention.- I

Figure 3 is a section taken on line 3-3 of Flgure 2 with parts in elevation.

Figure 4 is a rear view of the lock showi ing a locking positionf the latch member in dotted lines. Figure 5 is an enlarged viev1 of the lock taken on line 5 5 of Flgure 1.

As shown on the drawings: The reference numeral. 1 indicates a vehicle spare wheel carrier plate having rigidly secured thereon a threaded bolt 2.

Supported on the carrier plate 1 are a plurality of bolts 3 which are adapted to engage through the apertures in the disk 4 of a vehicle spare wheel 5. The inner pe;

ripheral margin of the wheel disk 4 is bent to form an outwardly projecting liange 6.

Engaged on the carrier bolts 3 to the out side of-'the wheel disk 45 is an apertured retaining late 7 having inte ally formed centrally t ereon a squared hu 8. The hub l8 is provided with an opening 9 through which the carrier bolt 2 projects. .A dan e 10 is formed on the outer'peri-phery of t e retaining plate 7 and contacts the wheel -disk 4. Cap nuts 11 are threaded onto the projecting ends of the bolts 3 to hold'the spare` wheel secured in position on the carrier.

yTo lock the spare wheel lonthecarrier to prevent stealing thereof, a lock is provided i for use on the middle or main carrier bolt 2. The lock' com rises a collar or sleeve 12 having integra y formed on one end thereof two diametricallly7 opposite lu or shoes 13 having straight inner faces'a apted to contact opposite faces of the hub 8 of the retaining plate 7. The Sleeve 12 is thus held against rotation-by means of the lugs 13.

vIntegrally formed on the inner peripheral surface of the s1eeve12 .are two oppositely disposed curveden surfaces 15.

VProjecting into the outer end of the sleeve 12'is thereduced inner end 16 of a cylindrical lock housing 17. The housing 17fis rojections or stops 14 having'-,

drilled axially at 18 and yis internally threaded at 19 to permit the housingA 17 tol be threaded onto the carrier bolt 2 by means of two opgositely directed arms or handl 20. The ousing 17 is .drilled to receive a l pin leek 21. having a barrel 22 provided with guard cap 25 onthe housing is limited by the length of the slots 26. The guard cap is provided with a middle opening 27 and with a curved vslot 28 in the front -face thereof. The slot 28 is provided to permit access to the key slot 2 3 when the guard cap is in the full linev position of Figure 2. When the lock is in position and it is desired to cover the key slot 23, the guard cap is rotated on the lock housing 17 .to

' position the slot 28 in the dotted line po- I pin lock 21 to sition of Figure 2, therebyl covering up the prevent dirt from clogging lup the key slot. y

After a spare Wheel 5 has been mounted upon the carrier and is held in place by. the retaining plate 7 and the bolts 3 andl nuts 11, the sleeve`12 is placed in position as shown in F igurel With the lugs 13 engaged'on opposite sides of the retaining plate hub 8 to hold the sleeve against -rotation. The lock housingl' is now threaded l' upon the main carrier bolt 2 vwith the latch or lookin lug 24 positioned as illustrated in the full ine osition of Figure' 4 so that it will clear' t e stop 14 in the sleeve 12.

After the'lock housing 17 has been threaded in place a key is inserted into the key slot 23 and rotated ahal turn to rotate the lock barrel 22 to move the lock lug 24: into the position shown in'Figure 3. The lock housing 17 is thus locked against rotation on the -bolt2 since the lug 24 will. contact one of the curved surfaces 15 of one of ythe 'sleeve stops 14 to prevent unthreading oit the' housing 17 from the bolt. 'llhe housing of course when locked can bepartially rotated back and forth to the extent of the space between the stops 14.

'. l am aware that numerous details oit construction may be varied through a' Wide y range Without departing from the principles of this invention, and l therefore do Anot vp lcirpose limiting the patent granted other-l wise than necessitated by the l" claim as my invention: 1. The combination With a carrier plate,

prior art.

and a key operated latch member in saidy sleeve, lugs thereon engaging said squared hub to hold the sleeve against rotation, stops formed'in said sleeve, a lock housing projecting into said sleeve adapted to be threaded onto said bolt, a latchmember in said lock housing, and key operated means for operating said Jlatch member to coact With said sleeve stops to lock the lock housing against rotation on said bolt.

3. The combination With av stationary vmember having a squared hub thereon, of

a bolt projecting through said hub, a sleeve engaging said hub, stops integrally'formed in said sleeve, a. -housing .projecting into said sleeve, and a rotatable member in said housing adapted in one position-to clear said sleeve ystops to permit the housing to be threaded onto said bolt'and in another position to engage said stopsto hold the l'giopsiiug against being unthreaded from said d. The combination with a bolt, of a nonrotatable sleeve engaged over said bolt, stops in said sleeve, a lock housing adapted to be threaded onto said bolt and project into said sleeve, and a key operated latch member in said housing ada ted When in release position to permitt e lock housing to be threaded onto the bolt or'unthreaded therefrom, and when in a latching position adapted to coact with said sleeve stops to hold the lock housing against being threaded onto the bolt or unthreaded therefrom.
